No Forest Falling Trees

A lightweight BepInEx mod for SULFUR that removes the sudden falling-tree scare from Forest Ambush events while keeping the encounter logic intact.

What This Mod Does

This mod targets Forest Ambush events such as:

Event_Forest_Ambush1
Event_Forest_Ambush2
Event_Forest_Ambush3

It removes the falling-tree presentation by neutralizing the visual and collision parts of the ambush trees.

The mod hides or disables:

Ambush tree renderers
Ambush tree colliders
Ambush TreeShakeable components
Ambush particle visuals
Ambush falling-tree audio volume

What This Mod Does NOT Do

This mod does not remove the Forest Ambush event itself.

It does not disable:

ForestAmbush Animator
Trigger
TriggerSpawner
NavMeshAnchor
Ghost scare events
Ghost spawns
Abomination
Normal enemy spawns
Ambush encounter logic

The goal is:

No sudden falling trees.
Same encounter logic.

Important Fix in 1.3.1

Version 1.3.0 had an issue where ghost scare animations could trigger, but the ghost itself might not spawn afterward.

This happened because the previous implementation disabled the ForestAmbush Animator on the Ambush Contents object.

Version 1.3.1 fixes this by keeping the Animator active and only hiding the falling-tree presentation.

Installation

Thunderstore / r2modman

Install the mod through Thunderstore Mod Manager or r2modman.

Make sure the required BepInEx dependency is installed.

Compatibility

This mod does not edit original game files.

It should be compatible with most mods unless they also modify Forest Ambush event objects.

Known Notes

If a future game update changes the structure or names of Forest Ambush events, this mod may need an update.

Uninstallation
